selects / joins across db's

hello...
i'm trying to join a table from one database with a table from
another database(both from the same server). It seems as if postgres
can't do this.

I don't know what the name of what i'm trying to accomplish is,
but i've seen it done in other databases with 'select * from
corpdb..table, storedb..table where ...'.

Thanks for any help.
